If a ball is dropped from a height of 18 feet, the function f(x) = 18(0.75)* gives the height
in feet of each bounce, where x is the bounce number. What will be the height of the
7th bounce to the nearest tenth of a foot?

Step-by-step explanation:

The given expression is

This exponential function represents the movement of a bouncing ball after being dropped.

represents the bounce number.

So, at 7th bounce means , replacing this value in the function, we have

Therefore, at the 7th bounce, the ball reached 2.3 feet height.

12cm

the answer is d

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
